Configuring JavaScript Debugger

Debugging JavaScript in RubyMine is supported through the JavaScript Debugger plugin. The plugin is activated by default. If the plugin is disabled, enable it on the Plugins page as described in Enabling and Disabling Plugins.

Debugging of JavaScript code is supported in Google Chrome and other browsers of the Chrome family.

To ensure successful debugging, it is enough to specify the built-in web server port and accept the default settings that RubyMine suggests for other debugger options.

In the Built-in server area, specify the port where the built-in web server runs. By default this port is set to the default RubyMine port 63342 through which RubyMine accepts connections from services. You can set the port number to any other value starting with 1024 and higher. If the Live Edit functionality is enabled, the JetBrains Chrome extension will also use this port to connect to the running page, see Live Edit in HTML, CSS, and JavaScript for details.

Optionally

Suppress calls to the files on the built-in server from other computers or from outside RubyMine by clearing the Can accept external connections or Allow unsigned requests checkbox respectively.
